tion of the invention, such as will enable others skilled in the art towhich it apper tains to make and use the same.

My invention relates to the type ofmachine which is known in the art asa setting out machine and more particularly my invention relates tomeans for supporting the work table for such a machine so that saidtable may have a certain amount of flexibility in its movement to andfrom the operating roll.

Another object of my invention is to so support the work table that thehide or skin may be presented to the operating or work roll in theproper manner for treatment.

The drawings show and the specification describes a type of machineparticularly adapted for treating or setting out the hank portions ofskins or hides but my invention is not limited to such a machine as mysaid invention is adapted for use in many other types of machines aswill readily occur to those skilled in the art.

In the accompanying drawings illustrating a type of my invention,Figure1 is a side elevation of a setting out machine; Fig. 2 is a sideelevation with the table shown in operating position; Fig. 3 is a frontelevation of the machine shown in Figs. 1 and 2, and Fig. at a view of ahide showing the flank portion which the type of machine shown in thedrawings is particularly adapted to treat.

In the said drawings similar numerals of reference refer tocorresponding parts in which 1 denotes the bed of an ordinary type ofsupporting frame provided with the uprights 2 and 3 and connecting piece4, it being understood that the parts 2, 3 and 4 are in duplicate onopposite sides of the machine and supported by suitable tie rods orbraces in such a manner as to produce a rigid supporting frame. A. workroll 5 provided, for instance, with helically arranged blades 5 issuitably mounted on the frame as on bars 6 (only one shown) carried bythe pieces 4 said operating roll being Specification of Letters Patent.

driven from both ends as by belts t, 8 passing over pulleys 9 9 attachedto opposite ends of the roll the said bolts 7, 8 leading to separatepulleys mounted on drive shaft 10 said shaft 10 being driven by anysuitable means as by pinion 10 carrying belt 11 leading to any suitablesource of power.

In front of the operating roll and upon opposite sides of the machineare mounted the slotted bars or supports 12, 13, said supports beingmounted on the base of the machine in such a manner that they may bereciprocated with relation to the operating roll. In the presentinstance I have shown bars 12, 13 as carried on the opposite sides of aplate or strip 14 hinged as at 15, 16 to the bed of the machine.

Pivoted to the frame of the machine as at 17 and 18 are another pair ofbars or rods 19 and 20 carrying at their upper ends the arched arms. 21and 22. These arched arms 21 and 22 are preferably of metal and in thepreferred construction are fastened at their flattened inner ends as byscrews 24: to the top of the table 23 as shown at 25. They are then bentoutward as at 26, 27 thus allowing room for swinging the hide as well asforming a support for the same. The arched arms 21 and 22 are fastenedto bars 19 and 20 by any suitable means as by bolts 27 and 28 and insuch a manner that there may be a slight pivoting movement of the archedarms'21 and 22 with respect to the bars 19 and 20. The table 23 may beconnected to the bars 12 and 13 in any well known manner as by means ofpins 29 and 30 working in slots in the side of the bars or supports 12and 13. Said table 23 can be of any approved construction, suitable forthe work. In the present instance I have shown said table as providedwith an upstanding rib or header 31 and as having a suitable bolsterconsisting, for instance, of a layer of felt 32 carried beneath aleather covering 33.

Having now described a preferred type of machine involving my inventionit will proceed to describe the operation of said machine. Theconstruction shown as heretofore set forth is designed preferably forthe setting out of the flanks of hides or skins and in the setting outoperation it is extremely desirable that a construction be provided thatwill allow great freedom of movement of the table to and from the workroll and that will also permit the operator,

whenever necessary, to vary the pressure of the table with respect tothe work roll when the same are in contact. In operation the flank 34 or35 of a skin as 36 (Fig. 4) is hung in the space between the head of thetable 23 and the work roll 5 while the remainder of the skin may beallowed to rest on the table 23. The operator then pushes said tableforward in direct-ion of the arrow in Fig. 1. This will cause thehelical blades 5 of the work roll 5 to come in cont-act with the flankportion of the skin and the continued forward movement of the table 23relative to work roll 5 will cause said flank portion to be pressedagainst the bolster on the bottom of table 23 in which position thehelical blades 5 on roll 5 will perform the setting out operation. Froman inspection of Figs. 1 and 2 the reciprocating movement of table 23with respect to work roll 5 will be readily apparent. Aside, however,from the forward and back movement of table 23 the operator may give thetable an up and down movement with respect to roll 5. In other words,the pressure of table 23 upon roll 5 may be made light or heavyaccordingly as the operator presses lightly or heavily upon said tablewhen it is in contact with the work roll. This variation in pressure ispermitted by making the arched arms 21 and 22 resilient to a greater orless extent so that they may be sprung more or less under pressure. Theconnections of the table 23 to bars 12 and 13 moreover and theconnections of the arched resilient arms 21 and 22 with the bars 19 and20 permit the pressure of the table 23 upon the work roll 5 to bereadily varied by the operator. It will further be observed that whenthe table 23 is in operative position with respect to the roll 5 thatsaid table 23 engages the top portion of said roll 5. This is consideredthe most important feature of my invention as by reason of this facttheoperator is enabled to get the exact pressure between the roll and thetable that may be required at any given time. Furthermore, by thisconstruction the skins are prevented from being mutilated, which isoften the case where the table is pressed directly against the roll.

Having thus described my invention what I desire to claim and to secureby Letters Patent of the United States is as follows:

1. In a machine of the character described, the combination with meansfor operating upon the hides and skins, of a reciprocable work-tablehaving supports with yielding means which normally hold the table out ofcontact with the hide operating means for permitting the reciprocablework-table to be pressed against and across the hide operating means.

2. In a machine for treating hides and skins, the combination of a workroll, a reciprocable table, pivoted means for supporting the table ofsuch length that the said table may be moved across the face of the workroll at a point above the horizontal axis of the said work roll.

3. In a machine for treating hides and skins, the combination of a workroll, a reciprocable table, pivoted supports for said table disposed onopposite sides of said work roll, the said pivoted supports being ofsuch length that the said table may be moved across the face of the workroll.

4. In a machine for treating hides and skins, the combination of a workroll, a reciprocable table, pivoted supports for said table disposed infront and at the rear of said work roll and resilient connections fromsaid table to the rear supports the said supports being of such lengththat the said table may be moved across the surface of the work roll.

In a machine for treating hides and skins, the combination of a workroll, a work table, pivoted supports for said table disposed on oppositesides of the work roll, the said supports being pivoted to the machineat a point below the axis of the work roll, and of such length that whenthe table is in operative position it will engage the work roll at apoint above the axis thereof. 6. In a machine for treating hides andskins, the combination of a work roll, a reciprocating table, pivotedsupports for said table disposed in front and at the rear of said workroll and resilient connections from said table pivoted to the rearsupports, the said supports being of such length that the said table maybe moved across the surface of the work.

In testimony whereof I afiix my signature, in presence of two witnesses.
